The Pig Pen patch This coveted award only goes to someone caught getting VERY VERY VERY dirty working on the 2926. Not just a little grease or paint on a finger . . . we mean legendary whole body, head to toe, into your underwear, penetrating everywhere with grit, grease, dirt, filth, muck, etc. on a scale that is unbelievable and hard to define. Only awarded upon the successful petition of the offended work crew to the President.
